sleepsacks for older toddlers

[nukuspot]

DD is 21 months and is super wiggly and hates being covered by blankets.  She's been in sleepsacks since we stopped swaddling and I'd love to continue them well into toddlerhood.  Her current one is 40 inches long and supposed to fit from 18-24mo, but she's tall and is growing fast.  I need to research longer sleepsacks for 2+.

The thing is the ones I can find that are for older kids still seem to only be 40 inches long, and they also are really expensive (149 for a merino wool one) or synthetic fleece (Halo) and I really don't want to use synthetics for sleeping. 

Am I missing something?  I tried Etsy but didn't see anything there worth mentioning.

Why not make one? Wazoodle has nice undyed bamboo and cotton fleeces and you could use your current sleepsack to draft a new pattern.

I'm so NOT a sewer.  It would come out like a potato sack.  Or worse.  I'd pay for someone talented to sew me one, though!

I'd make you one if I wasn't so behind in all the other (now urgent) sewing projects. Like the larger diapers - good thing ds has such slim hips!
